using the IP-NINJAR Configurator (configuration software for IP-NINJAR).
For operations from the IP-NINJAR Configurator, refer to the User Guide of IP-NINJAR Configurator.
Please contact us to download the IP-NINJAR Configurator.
Note:
When using LAN communication to control the NJR-01UHD, the terminal software cannot be used.

3.4 Connecting LAN cable
When connecting a LAN cable to NJR-T01UHD/NJR-R01UHD/NJR-CTB, avoid making a network loop.
The NJR-T01UHD and NJR-R01UHD send broadcast packets periodically for the purposes of internal system
management.
*A broadcast storm occurs when a network is overwhelmed by continuous broadcast traffic resulting in a
network meltdown.
During installation, it is important to avoid the creation of network loops. Contact IDK if you require assistance
with network implementation.

4 Command
4.1 Summary
A command consists of “@” (“40” in hexadecimal), 3 or 4 one-byte alphabetical characters (upper and lower
cases) followed by parameters (one-byte numbers). For some commands, multiple parameter values can be
specified. Processing is executed by sending a delimiter at the end of the command.
Example:@SDT,1,1,1,10000
“,” (a comma, “2C” in hex) is indicated between a command and parameter and between two parameters.
“ ” is indicated as a delimiter CR LF (return+line feed, “0D” and “0A” in hex).
■If an error occurs:
An error response is returned if an undefined command or inappropriate parameter is included.
Example:@SDT,1
@ERR,1
■Using as HELP
If only delimiter is sent, command list as the help command is returned.
Example:
---------------- HELP (1/2) ---------------

4.4 Parameter input format
Parameter input formats are common for each setting.
If a command is input from the RS-232C connector of NJR-T01UHD/NJR-R01UHD or from the LAN
connector using the
IP-NINJAR Configurator (Software for setting IP-NINJAR), “1” (fixed) is specified to “ch” (channel) because
only one NJR-T01UHD/NJR-R01UHD can be controlled.
If a command is input from the NJR-CTB, any channel can be specified because multiple
NJR-T01UHD/NJR-R01UHD devices that are connected over a network switch can be controlled.
Example:
Format
@SAM, device, ch, port, mute
Parameter
device: Model
1 = NJR-T01UHD, 2 = NJR-R01UHD
ch: channel
1 to 512 = Channel 1 to Channel512
If a command is input from the RS-232C connector of NJR-01UHD or from the
IP-NINJAR Configurator, “1” is set (fixed).
